The present disclosure relates generally to agricultural field maps and more particularly to mapping zones of an agricultural field map.
Agricultural operations benefit from the use of controls and automation. Automation requires preplanning to ensure that operations are performed as required. For example, an automated agricultural machine requires information pertaining to where agricultural material should be applied and the rate at which the agricultural material should be applied.
In addition, regulations require documentation of the application of agricultural materials. The legal requirements in terms of application are becoming more stringent. More and more often farmers need to change the application rate depending on different types of adjacent structures like hedges or waterways. Typical application systems can adjust only the application rate. What is needed is an easy and efficient method to identify where agricultural materials should be applied, identify application specifics pertaining to how the agricultural material should be applied to an identified area, and document the application of the agricultural material to the identified area.
In one embodiment, a method for zone mapping and tracking the application of agricultural material to zones of a geographic area includes displaying a geographic area of interest to a user via a display of a zone mapping system. The user identifies a zone of the geographic area that is to be treated using agricultural materials. The user identifies the agricultural material to be applied to the zone and an application plan for the zone is determined. Determining the application plan for the selected zone includes identifying a feature in the zone and identifying an offset from the feature based on a type of the feature and the agricultural material to be applied. Geographic coordinates bounding an area adjacent to the feature are determined based on the offset identified. The application plan is then transmitted to an agricultural machine which operates substantially in accordance with the application plan. The agricultural machine tracks the application of the agricultural material and transmits this information to the zone mapping system. The application information is then stored in a database associated with the zone mapping system for later retrieval in response to requests for the application information.
The image of geographic area 100 can be a satellite image or aerial image. The image of geographic area 100 can also be a representation of an area generated by a user drawing geographic area 100 while viewing the actual geographic area or viewing a satellite image or an aerial image of the area. Information pertaining to geographic area 100 can also be obtained by sampling via local scouting or generated by agricultural application data input by a user.
In one embodiment, geographic area 100 is displayed to a user via a display of a zone mapping system. The zone mapping system displays an image of geographic area 100 and a user can identify various zones within geographic area 100 using, for example, a touchscreen display.
In one embodiment, various features of geographic area 100 are automatically recognized by the zone mapping system. For example stream 102, depression 104, planting field 106, pond 108, path 110, and marsh 112 can be detected in the image of geographic area 100 using one or more of a variety of object recognition techniques such as, for example, edge matching, greyscale matching, etc. Similarly, additional features can be automatically recognized as well.
In one embodiment, automatic recognition can be augmented or replaced by the features of geographic area 100 being identified and designated by a user. For example, a user can trace the features and then enter an identification of what the traced feature represents. In one embodiment, a file containing various polygons can be imported and a user can select a polygon to enclose an area. Geographic features can also be identified by an operator driving a machine around a field or an internal area and a polygon surrounding the area can be generated based on the movement of the machine. In one embodiment, a lines can be drawn on a coverage map to encompass all covered areas.
The user may designate various zones of geographic area 100 by drawing polygons around desired areas using a touchscreen or mouse.
After the user has identified a zone, such as zone 302, the user can select one or more treatments to be applied to the identified zone. For example, a user can select to plant seeds in order to grow a crop in the selected zone. The user can also select treatments such as pesticides, growth promoters, fertilizer, or other treatments to be applied to the selected zone.
Crops can have certain crop requirements regarding the use of treatments. For example, a certain amount and concentration of pesticide over a specified area may be required to be applied to a certain crop. As such, a pesticide for soybeans, for example, may be required to be applied at a rate of two ounces per square yard at a concentration of fifty percent in a particular area.
In addition to crop requirements, certain application restrictions may be defined by a government entity or a manufacturer of a treatment regarding application of the treatment. For example, a pesticide may be restricted from being applied within a certain distance from flowing water, such as a stream. An application restriction regarding the application of the pesticide can indicate that the pesticide should not be applied to an area within five feet of the flowing water. Application restrictions, in one embodiment, pertain to the restriction of agricultural materials to an area for any of a variety of reasons. Application restrictions can be defined by a government entity, manufacturer, and/or supplier of the agricultural materials.
In addition to crop requirements and application restrictions, it may also be desirable to have the zone mapping system identify areas that an agricultural machine should not attempt to traverse, such as a pond, stream, or depression. For example, a particular agricultural machine may not be designed to traverse water over a certain depth. As such, a pond having a depth greater than the depth that the agricultural machine was designed for should be avoided. In addition, a particular agricultural machine may not be designed to operate on slopes having an incline over a threshold value. As such, a slope having an incline over the threshold value should be avoided. In one embodiment, restrictions regarding operation of an agricultural machine are referred to as machine restrictions. Machine restrictions can be defined by a government entity, machine manufacturer, and/or a dealer of the agricultural machine.
After the user selects a treatment for the identified zone, the zone mapping system designates certain areas where the treatment should not be applied. In one embodiment, areas where the treatment should not be applied are based on crop requirements, application restrictions, and/or physical obstacles to be avoided (e.g., slopes of depressions, bodies of water, etc.)
Stream boundary 402 is based on an offset from each side of stream 102 that is required by an entity, such as a government, to prevent the agricultural pesticide from contaminating the water of stream 102. For example, a governmental regulation may restrict the application of the agricultural pesticide from being applied closer than five feet from stream 102. As such, stream boundary 402 is located five feet from each side of stream 102.
Depression boundary 404 is based on an offset designated by an equipment manufacturer regarding operation of the agricultural machine that will be used to apply the agricultural pesticide. For example, the equipment manufacturer may indicate that the agricultural machine is not to be operated on slopes or on slopes having an incline greater than a threshold. For example, an equipment manufacturer may indicate that a particular agricultural machine should not be operated on slopes having a grade greater than, for example, seven percent. Depression boundary 404 identifies how far from depression 104 the agricultural machine should operate in order to prevent a potential accident, such as a rollover of the agricultural machine.
Pond boundary 408 is based on an offset from the edge of pond 108 that is required by an entity, such as a government, to prevent the agricultural pesticide from contaminating the water of pond 108. For example, a governmental regulation may restrict the application of the agricultural pesticide from being applied closer than five feet from pond 108. As such, pond boundary 408 is located five feet from each side of pond 108.
Path boundary 410 is based on an offset from the edge of path 110 that is required by the manufacturer of the agricultural pesticide to be applied in order to prevent humans or animals from being exposed to the agricultural pesticide by walking on path 110. For example, an offset of fifteen feet from an area where humans or animals travel may be specified by the manufacturer of the agricultural pesticide.
Marsh boundary 412, in one embodiment, is based on an offset designated by a government to prevent the agricultural pesticide from contaminating marsh 112. In one embodiment, marsh boundary 412 is based on an offset designated by an equipment manufacture regarding operation of the agricultural machine that will be used to apply the agricultural pesticide. The offset may be designated by the equipment manufacturer to prevent operation of the agricultural machine in water or operation over ground that may not be sufficiently stable to support the weight of the agricultural machine. In one embodiment, one offset applies to how close a machine can be to a natural feature, such as a marsh, and another offset applies to how close material can be applied to the natural feature. It should be noted that, in one embodiment, when two similar offsets apply to a feature, the larger offset is used. For example, when two offsets pertaining to how close a machine can be to a natural feature, or when two offsets pertaining to how close material can be applied to the natural feature, the larger of the two offsets that pertain to the same operation is used.
In one embodiment, application information such as crop requirements and application restrictions are stored in a table in an application/restriction database. Zone and feature information are stored in a table in a zone database. The creation of zones can be performed when material to be applied is being loaded. Since each material to be applied can have different restrictions, the application zones can vary based on the material to be applied. In one embodiment, multiple restrictions apply to a particular material. For example, droplet size, application rate, tillage depths, application type and other restrictions may apply to a particular material.
In one embodiment, application details can be used to modify the application of materials. The application details can be input by a user and/or stored in the application/restriction database 714. In one embodiment, application details pertain to droplet size that is to be used when applying a particular liquid. Droplet size can be controlled for different applications. Droplet size affects the distribution of the liquid being sprayed. For example, smaller droplets can create a coating film while bigger droplets are not blown away by wind or evaporate before touching the crop to which the liquid is to be applied.
Application/restriction database 714 includes tables of records pertaining to application information.
In one embodiment, application information and restrictions are treated as individual layers and the application requirements or restrictions of each layer are addressed individually and in their context with respect to other layers. For example, in one embodiment, a first layer pertains to an application rate. With respect to the first layer, high pressure is used to produce fine droplets that will create a good coating on a crop to which the liquid is applied. A second layer pertains to water that is protected and a restriction associated with that region identifies a limit of droplet size that can be applied. When the machine enters the region to which that restriction applies, the droplet size of the liquid as it is applied is changed by making the droplet size larger (e.g., coarser) than the size without the restriction. The larger droplet size reduces the potential of the droplets to wind drift into the water located in the region. In one embodiment, the larger droplet size is achieved by lowering the pressure applied to the application nozzles. The lower pressure reduces the flow through the nozzle. In response, other parameters may be adjusted in order to maintain the correct flow and/or application rate. For example, the reduced flow through a nozzle due to a decreased pressure may be compensated for by reducing a speed of the machine spraying the liquid, changing to a nozzle having a higher flow rate (e.g., a nozzle that produces a, using a pulse width modulation with a higher duty cycle, using an additional nozzle.
Additional layers may modify operation of the machine as well. For example, a third layer may cause a speed at which the machine travels to be reduced when entering an area that is sloped in order to prevent the machine from rolling over. This slower travel speed may require adjustment of other parameters, such as flow rate, in order to compensate for the change in speed and maintain a specified application rate.
In one embodiment, zone and feature location information are stored in a table in a zone database 712.
In one embodiment, the coordinates identify multiple points of a polygon. For example, record 602 which pertains to a polygon identified as zone A and is associated with coordinates A-E. Coordinate A 622 identifies a first point of the zone A polygon. Coordinate B 624 identifies a second point of the zone A polygon and Coordinate A 622 and coordinate B 624 together identify a side of the zone A polygon. Similarly, coordinate C 626 identifies a third point of the zone A polygon and coordinate B 624 and coordinate C 626 together define another side of the zone A polygon. Coordinate D 628 identifies a fourth point of the zone A polygon and together with coordinate C 626 define another side of the zone A polygon. Coordinate E 630 identifies a point of the zone A polygon and together with coordinate D 628 defines a side of the zone A polygon. It should be noted that coordinate E 630 has the same coordinates as coordinate A 620. In one embodiment, this indicates that there are no additional coordinates and the identified coordinates together form a closed polygon. In another embodiment, a string of stored coordinates defining a polygon ends with an end message that signals the last coordinate identified is the final coordinate defining the polygon. In yet another embodiment, a polygon is identified by two stored coordinates that span an area and any coordinates between the two stored coordinates are considered relative vectors inside this spanned area. Zone A 602 and feature A 604, feature B 606, feature C 608, and feature D 610 can represent zones and features in a geographic area such as zone 302, stream 102, depression 104, planting field 106, pond 108, path 110, and marsh 112 as shown in
Memory 706 is electrically connected to controller 702 and can comprise one or more types of random access memory, both volatile and non-volatile. Storage 710 can contain databases pertaining to zone mapping. In one embodiment, storage 710 contains zone database 712 which stores information pertaining to zones of a geographic area (such as zone 302 of geographic area 100 shown in
Input/output 708 can comprise various inputs, such as a keyboards, touch screens, etc. Input/output 708 can comprise various outputs, such as displays, lights, alarms, etc. The inputs and outputs of input/output 708 are electrically connected to controller 702. Network interface 716 is electrically connected to controller 702 and facilitates communication with controller 702 via various devices. Network interface 716 can be various connection types including wired and wireless. Network interface 716 can also utilize a variety of communication protocols. Network interface 716 allows controller 702 to communicate with a variety of devices.
In one embodiment, network interface 716 allows controller 702 to communicate with a variety of different devices that can each be associated with a different entity. In one embodiment, controller 702 is in communication with an agricultural material manufacturer device 718 via network interface 716 in order to receive application and restriction information related to agricultural materials. Controller 702 is also in communication with an equipment manufacturer device 720 via network interface 716 in order to receive operation information regarding equipment. Controller 702 is also in communication with a government entity device 718 via network interface 716 in order to receive information pertaining to restrictions related to the application of agricultural materials.
In one embodiment, controller 702 is in communication with agricultural machine 724 via network interface 716. Agricultural machine 724 is equipped with a machine indicator 726 which, in one embodiment, is a computer that can be used to track and/or control operation of agricultural machine 724. In one embodiment, machine indicator 724 includes additional components, such as components that indicate an orientation of agricultural machine 724 and the position of working elements (e.g., implements) of agricultural machine 724. Agricultural machine 724 can include a global navigation satellite system (GNSS) receiver, also referred to as a global positioning system (GPS) receiver 728. GPS receiver 728 is electrically connected to machine indicator 726. GPS receiver 728 determines the location of its associated antenna and transmits the location information to machine indicator 726. Operation information and location information pertaining to agricultural machine 724 can be transmitted to controller 702 via network interface 716. In addition, zone maps and application/restriction information for a particular geographic area can be transmitted from controller 702 via network interface 716 to machine indicator 724.
At step 806, input is received from the user identifying an agricultural material for application to the identified zone. In one embodiment, the user can select from a plurality of agricultural materials shown in a pop-up or drop down menu. The agricultural materials identified in the menu can be selected from agricultural materials identified in application/restriction database 714. Alternatively, a label located on packaging containing the agricultural materials can be scanned using a hand-held device, such as a scanner. In one embodiment, a user can enter identification information pertaining to an agricultural material and information concerning that agricultural material can be obtained from agricultural material manufacturer device 718 and/or government entity (e.g., federal, local, regional, etc.) device 722 shown in
Next, an application plan is determined for the identified zone. In one embodiment, determining an application plan comprises identifying a feature, identifying an offset, and determining geographic coordinates of an area adjacent to the feature based on the offset. At step 808, a feature in the zone is identified as described above in connection with
At step 814, the application plan is transmitted to an agricultural machine. In one embodiment, controller 702 transmits the application plan to machine indicator 726 of agricultural machine 724 via network interface 716. The transmission can be via a wired or wireless connection. The agricultural machine, such as an agricultural sprayer then applies the agricultural material to a geographic area identified by the selected zone. As the agricultural machine operates to apply the agricultural material in accordance with the application plan, the machine indicator of the agricultural machine records information pertaining to application of the agricultural material such as location and related application rate. This information gathered by the machine indicator is referred to as application data. In one embodiment, the application data is generated based on operation of the agricultural machine in accordance with the application plan. However, the application data can deviate from the application plan for various reasons such as obstacles located in a zone, operator error, etc.
At step 816, application data is received from the agricultural machine. At step 818, the application data received from the agricultural machine is stored in application history database 730. The information stored in application history database 730 can be provided to various entities in order to show how agricultural material was applied to the zone. For example, a government entity may request information from a user pertaining to the application of a particular agricultural material. The user can find information pertaining to all applications of the particular agricultural material that have occurred and provide this information to the government entity. In one embodiment, recorded data can also be used for determining desired application rates in further application areas/steps.
In one embodiment, a method for mapping zones and generating application plans begins with identifying a geographic position and movement of an application machine. The application machine is identified and its status and orientation are determined. A map showing the machine and the area surrounding the machine is shown on a display. Local data, such as an existing boundary, zone, or obstacles, is also displayed on the map. New features within the area displayed on the map are identified and coordinates for the new features are determined. Information pertaining to application of material to an area of the map is loaded and the material to be applied to the area is identified (e.g., by user selection of a product or scanning of a package of product using a hand-held device). Information pertaining to the material is then obtained from one or more sources such as the product manufacturer, machine and/or implement manufacturer, a material advisor, or a government entity. Based on the information that is obtained, an offset width and, in one embodiment, a restriction type are determined and the information is applied to the area displayed by the map. Application information (rates and restrictions) are determined for zones of the map and the material is applied in accordance with the determined application information. In one embodiment, the application information is determined on a machine separate from the agricultural machine. In those embodiments, the application information is transmitted to the agricultural machine. In one embodiment, the agricultural machine records data pertaining to how the material is applied to an area based on the application information. It should be noted that the actual applied material may differ from the intended or desired application determined as described above due to various issues that prevent desired application. In one embodiment the data recorded by the agricultural machine pertaining to the material applied to the area identified by the map is stored in a location (e.g., an application history database).
